i lived at home my brother (who i shared a room with) used to do this all the time, i recorded him once! he said..
"slam me up the wall darling, and if you play the cards right you'll get a piece of the action.!"
i still have the recording...dont want to think about what he did next, i shut my eyes tight and put a pillow over my face..
:(

do any annoying things whilst sleeping, partly because i find it extremely hard to get to sleep. But i did briefly on holiday in france with some friends. I don't know why, but i took up yelling, i would yell whole sentences.
